Use the supplied dropper to wet the suspected stain or area with 1-2 drops of the liquid from bottle number one. Let the liquid absorb into the fabric or stain and proceed to step two.

Blot the wetted stain or area by holding the paper down gently until the paper is thoroughly wetted. This transfers any biological material that may be present from the article being tested to the test paper. After absorbing the suspected stain, turn the paper over so that the side that was touching the stain is now facing up. Let the paper dry and proceed to the next step. 

Apply 2-3 drops of the reaction component from bottle number two directly to the paper where you transferred the stain.
